Belden Virtual Firewall Deploy anywhere—protect anything

Deploy 360° cybersecurity wherever you need it—as a hardware-agnostic solution

in your data center. Deliver deep packet inspection (DPI), intrusion prevention and

protocol awareness to protect industrial environments.

• Expose elusive OT network threats with multi-layer traffic analysis that detects

what traditional firewalls miss.

• Stay ahead of evolving regulations with built-in enforcement controls and

automatic firmware updates that ensure compliance.

• Lower total cost of ownership with a single hardware-agnostic cybersecurity

solution and flexible licensing tiers.

Key Features

• Quick deployment on VMware or Microsoft Hyper-V or QEMU/KVM;

installs in minutes without dedicated hardware.

• Advanced Layer 7 inspection, including identity awareness, application awareness

and industrial protocol awareness for OT networks.

• High-throughput architecture optimized for industrial traffic patterns without

sacrificing inspection depth.

• Deep Packet Inspection (DPI) enforces popular industrial communication protocols.

• Stateful inspection firewall for improved security decisions regarding data traffic

between networks.

• Intrusion detection and prevention monitors data traffic for anomalies and malicious

patterns, alerts users and SOCs, and triggers actions.

• Centralized management of firewalls can be initiated remotely and at scale.

• Built with Belden OS enabling end-to-end security, unified visibility, and policy-based

enforcement.

• Belden OS seamlessly integrates various

Belden products, ensuring consistent management and threat intelligence sharing.

• Designed for compliance with IEC 62443-4-2 SL-1 and SL-2. and the EU Cyber

Resilience Act.

Belden Virtual Firewall deploys wherever you need protection—in your data center,

on edge

devices or within virtualized infrastructure. Built with Belden OS, it integrates

seamlessly with your broader industrial security architecture.

Your benefits

Industrial networks face increasing cyber threats as OT and IT environments

converge. Traditional firewalls can’t effectively handle emerging cyber threats

and OT uptime requirements.

The Virtual Firewall provides next-generation capabilities, including Deep Packet

Inspection (DPI) for industrial protocols, real-time intrusion prevention and

application aware filtering that protects without disrupting operations.

Deploy the Belden Virtual Firewall in your data center or on ruggedized hardware.

Unified management gives you centralized control across your security infrastructure,

while flexible licensing lets you scale protection as your needs evolve.

Applications

Built with Belden OS, the Belden Virtual Firewall delivers advanced capabilities

to safeguard critical infrastructure across industrial OT and IT environments.

Its virtual format provides deployment flexibility—run it as a hardware agnostic

solution in your data center or on your 19-inch rack hardware for power substation

applications.

Markets

The Belden Virtual Firewall provides mission-critical protection for industrial

organizations with sophisticated, virtualized operations. It defends against cyber

threats while maintaining the network uptime that OT environments demand.

Target industries include energy, automotive manufacturing and discrete

manufacturing, where IT/OT convergence creates new attack surfaces.

Built with security-by-design principles, the Belden Virtual Firewall ensures

compliance with IEC 62443-4-2. EU CRA, FCC and CE requirements—preparing

your infrastructure for evolving regulatory standards.

Choose the license tier that matches your security requirements:

• Essential: firewall protection with accelerated throughput, full VPN functionality

and edge computing; ideal for machine builders.

• Advanced: adds DPI, high-availability features, antivirus protection and web filtering.

• Pro: complete functionality, including dynamic routing, intrusion prevention,

an additional web application firewall (WAF) and identity awareness.
